Attempt to clear lockout as described above. If this fails, contact a Whale Authorised

Service Engineer.

When using the Water Heater in winter, ensure the flue is not blocked by snow or fallen leaves etc. When not in use,

ensure that the Water Heater is drained. This is particularly important during the winter months as a precaution

against freezing. To drain, switch off the water pump at either the pump switch or main switch. Open all the hot water

taps in the vehicle and operate the drain valve fitted in the system. The drain valve must be left in the “open” position

to ensure all the water drains out.
